"Economic value is the measurement of the benefit derived from a good or service to an individual or a company. Economic value can also be the maximum price or amount of money that someone is willing to pay for a good or service. As a result, economic value can be higher than market value".

What price a seller sets for a product is based on neither of those cases.

It can be widely different from the actual market value the item could fetch (as per my example).

And it's also not the value the buyer gets ("the benefit derived from a good or service to an individual or a company"). Again in the example I gave this is many orders of magnitude bigger than the selling price.
